.Net /4GT
in [CSharp]

From: mk on 27 Nov 2006 04:46 Hi. Does anyone know how to set the IMAGE_FILE_LARGE_ADDRESS_AWARE bit for C# apps? It appears that the link switch /LARGEADDRESSAWARE will do it for C++ apps, but I can't seem to find anything for C#. I want to enable /4GT on a w2k3 server with 8GB Ram, so that one process may avail of more memory. Thanks.

But, make sure you understand the ramifications of doing this, in general you only want to enable this on dedicated servers. The reason is that when enabling /4GT, you are effectively reducing the OS address space from 2GB to 1GB, this may introduce several issues when the OS runs out of memory. Willy.

That's exactly what I was looking for, we'll be doing extensive testing/stressing on the machines in question, so there's no guarantee that we'll use it, but I think for our caching services which are pretty lightweight but extremely memory-intensive it may do the job nicely. Thanks again. "Willy Denoyette [MVP]" wrote: > "mk" <mk(a)discussions.microsoft.com> wrote in message > news:D3C77B29-7222-4154-AA70-DB30C7864AFD(a)microsoft.com... > > Hi.

Your best bet (obviously) is to get a 64-bit machine, and run your code in 64-bit land. You're only going to get (at best) another 1GB or so of memory available to your managed heap. You will won't be able to access all 8GB, you're stuck with just 3 gigs. -- Chris Mullins, MCSD.NET, MCPD:Enterprise http://www.coversant.net/blogs/cmullins
